The synthesis pathway for RNA nucleotides utilized multiple amino acids as reactants. DNA nucleotides can then be synthesized from RNA in metabolic reactions. The Miller-Urey experiment showed amino acids can be produced from gases in the Earths early atmosphere and environmental conditions (heat and lighting). A. Order the most probable chronological sequence (1-3) that the three biological polymers appeared on Earth. B. Describe your rationale for your ordering.
